ROAD EMBANKMENT ON PERMAFROST IN AREAS WITH SNOW TRANPORT Russian patent published in 2021 - IPC E02D17/18 

FIELD: road construction.

SUBSTANCE: invention relates to the field of construction of road embankments on permafrost in areas of active snow transport by wind flow: blizzard snow transport. A road embankment on permafrost in areas with drift-snow transport contains an embankment body located on the natural surface of the soils of the bases and a cooling system for stabilizing the temperature regime of permafrost soils, and the embankment body is made in cross-section in the form of a trapezoid with an upper small base for the passage of transport, bounded on the sides by break points, and a lower base, with the formation in winter on the slope parts of the embankment and adjacent sections of a snow prism, representing a triangle in cross-section. The cooling system for stabilizing the temperature regime is made in the form of a system of snow-blowing structures installed on the leeward side along the sole of the embankment slopes. Each element of the snow-blowing structure is made in the form of a snow-blowing fence with a height of h_f with a lower clearance of h_cl, determined by the formula: h_cl=h_z/3, m.

EFFECT: reduced volume of earthworks, which leads to a reduction in the cost of construction and operation of the road embankment.
